Staying at Cornell and adding a bit of celebrity for today’s Top 200 Photo.

photo #107 is:

Bill Nye got his undergraduate degree in mechanical engineering from Cornell University. In an example of the awesome professors you can have at Cornell – one of his professors was Carl Sagan! Cornell has a program that invites alumni to come back once a semester and teach a class for a day. Here Bill Nye was teaching my Physics 213 class. My wife had alumni and former attorney general Janet Reno teach one of her classes. Anyway, I knew Bil Nye both from his appearances at the end of the animated Back to the Future show and from his show Bill Nye the Science guy, which I used to watch religiously.
